I am working on a home made electromechanical actuator to replace the vacuum actuator on the front axle of my Jeep Cherokee.
The vacuum actuator isn't the greatest and I have replaced it and the system lines few times.
SO I figure, I know what force the vacuum actuator is putting out, I know the stroke length, I have stuff to make this, why not?
BUT I want to get the physics right in my head first.
SO, Let's say I have a spring that will push a cylindrical magnet away from the shift fork, and a solenoid made from wiring that push the magnet into the shift fork. Which engages the hubs.
I already figured out the spring portion and drawn out the magnetic field interaction.
Does anybody have an equation to get an accurate (or conservative) repelling force for the solenoid and the magnet?
I haven't really found a good source, wiki has some, but I don't trust wikipedia.
Thanks
